APPLICATION OF EMF SHF IN PROCESSING TECHNOLOGIES FOR VEGETABLE MATERIAL AND SECONDARY RESOURCES
Description
The article analyzes the proprietary methods of processing of vegetable raw materials and secondary resources with the use of electromagnetic fields (EMF SHF). Analysis of the database of Rospatent World Intellectual Property Organization led to the conclusion that EMF SHF used in the processing of vegetable raw materials in the following processes: drying, reduction of microbial contamination (decontamination), juice production and extraction. It is established that the application of EMF SHF is the most effective in preparation for drying a plant raw material and not directly at the stage of drying, thus reducing the loss of heat-labile active compound in the drying process, and therefore obtain a finished product of higher quality and nutritional value. The patented methods of extraction of vegetable raw materials extraction process performed that extracting directly EMF SHF does not allow pre-hold inactivate enzymes contained in the raw material and lead to undesirable oxidative and hydrolytic processes, and hence a decrease in the yield of extractable substances in the extract and the deterioration of its quality . Therefore, as in the case of drying plant material, EMF SHF can be more effectively used in preparation for an extraction process. Based on the analysis, it was concluded that the relevance of developments in the field of technologies of processing of vegetable raw materials and secondary resources using EMF SHF at the stage of their preparation for such basic processes - drying, extraction, etc.

MODERN WAYS OF INULIN PRODUCTION FROM PLANT MATERIALS
Description
The article presents the results of the patent research in the field of modern production technologies of Inulin from plant material. It has been established that the differences of the currently known methods of production of inulin are concluded in selecting raw materials pretreatment inulin-containing modes type extractant and extraction methods, methods of purification inulincontaining extract and methods for producing the final product. A significant amount of Inulin production methods is based on use of freshly feedstock. A number of methods have been patented involving the extraction Inulin from plant raw materials previously stabilized by drying. In most of the methods, inulin extraction is carried out at elevated temperatures with water or aqueous salt solutions. Several technologies involve extraction with organic solvents at low temperatures. Have been patented several processes in which the extraction is replaced by a separation process using inulincontaining juice and physical and mechanical methods. Some of the known processes provide for the extraction process to further operations, such as blanching vegetable raw materials, sonication, vibration impact, processing enzymes. The most promising direction to improve manufacturing technology of inulin from fresh plant raw materials is to conduct research on the use of electromagnetic fields at microwave frequencies, the inactivating effects of which on enzyme systems is an established fact that, in turn, would eliminate the use of chemical agents for inactivation of oxidative enzymes. In addition, considering that more effective are the methods for the preparation of inulin from freshly harvested plant material, are relevant researches on development of innovative technologies to prepare it for storage and its storage, which will provide inhibition of unwanted biochemical and microbiological processes that occur during storage and lead to a loss of inulin

Description
We have illustrated multiple factor analysis of the dynamic friction coefficient of the friction units in tribosystem and tribounits under laboratory conditions. As the tribosystem we had a model band-block brake with regime parameters of the control handle tension of the brake and brake work. By using the method of the mathematical planning of the extreme experiments, we have obtained functional dependence of the dynamic friction coefficient of the variable parameters in the form of a second-order polynomial, which adequately describe the processes under study. As tribounit at the micro- and nanoscale there was the reference change of the dynamic friction coefficient of the pair "Retinax FC-24A – Steel 35HNL" as a function of surface temperature, the values of which correspond to certain laws, based on the rise and fall of the characteristics of the dynamic friction coefficient. We have made the evaluation of the dynamic friction coefficient on the principle of the superposition with the multiple factor analysis of the following parameters: the process of forced cooling and heating; the processes of the polarization and depolarization in the contact patch of the micropoints of friction pairs; the type of the contacts of the micropoints depending on the work function of the electrons and ions from materials; the formation of primary and secondary structures on the surfaces of frictional contact; the destruction and restoration of the pellicles on surfaces, etc. We have analyzed the results of the studies of changes of the dynamic friction coefficient on the macro-, micro- and nanoscale and we have found the basic factors affecting its value

ANALYSIS OF CIRCULAR INSTRUMENTS WITH FOUR IN-LINE ARRANGEMENT OF THE SPHERICAL DISKS
Description
The main direction of reducing the cost of soil treatment based on resource-saving technologies is the transition to surface treatment of soil with disk tools. Double-row and four-row disc tools are manufactured. Four-row tools significantly increase tillage intensity. In the disk tools, the spherical disc is fixed on the individual pole. Disc headers are equipped with a rigid adjustment fixing the standalone pole to the frame. Recommended operating speed is up to 12 km/h. The advantage of a disc header over the disc harrow is as follows: winding plant residues on the axis are excluded. Disc mulchers are equipped with a spiral bar on which a spherical disk is mounted. The presence of the elastic element allows the working unit to do lowfrequency oscillations during movement. The result of processing is the formation of mulch in the layer of soil, which is a mixture of plant residues and soil particles with a diameter of up to 25 mm. To assess the effectiveness of the disc mulcher and the disc header a unit is composed. The initial data for calculation are as follows: tractor HTZ-150K, the resistivity of the soil is 6 kN/m, disk tool working width is 4 m, operating speed of the disc header is 12 km/h, operating speed of the disc mulcher is 15 km/h. Technical and economic performance of these units is defined during disking the soil. The choice of energy-saving operating regime was made in a well-known manner. Theoretical value of slippage of the leading tractor with disk mulcher was 6%, against 9% with the disc header. Working speed of the mulcher made up 14.07 km/h against 10,89 of the disc header. The performance of the unit with the mulcher made up 16.21 hectares, disc harrow performance is 12,54 ha. Fuel mass flow of mulcher decreased by 29% and made 9.68 kg/ha. Using mulcher for surface treatment of the soil allows to reduce the tillage energy costs thanks to resource-conserving technologies

THE STUDY OF SELF-BALANCED POTATO SORTING MACHINE WITH LINEAR INDUCTION DRIVE
Description
In the article we have considered the self-balanced potato sorting machine differing from existing designs of self-balanced potato sorting machines with an oscillatory electric drive. That drive uses a linear induction motor. As the counterbalancing device, the method of the duplicating mechanism is applied. The duplicating mechanism is a specular reflection of the main working body, and also participates in technological process. Its application in the drive of machine allows not only to increase efficiency of cleaning, drying and sorting of potatoes, but also to increase reliability of sorting installation that corresponds to the newest tendencies of development of technology. We have brought the mathematical model of the offered electric drive of potato sorting machine, which is implemented in the environment of object and visual modeling of Matlab |Simulink|. The mathematical model allows investigating influence of parameters of the linear induction electric drive on parameters of oscillatory process of working body in dynamics. The developed technique of research and the created experimental potato sorting machine with the linear induction drive have confirmed theoretical researches. The main kinematic sizes of machine and technical parameters of individual nodes are determined. It is shown, that the efficiency of inertial transportation can be increased for 20% in comparison with the classical drive from the motor of rotation. Results of research will allow to realize energetically and technologically effective potato sorting machines with the linear induction drive

MODULATED STATOR WINDINGS OF THE MOTOR FOR FAN DRIVES
Description
In poultry industry, animal breeding, greenhouses and vegetable stores a significant amount of fans with asynchronous motors is used to create a microclimate. The fan speed of the fan should be regulated in order to improve the efficiency, so the multispeed motors are used for the fan drives. Line produced two-speed motors with a proportion of the poles number 1:2 have a polar-switched Dahlander stator winding. Two-speed motors with a proportion of the poles number 3:2 and 4:3 have only one stator winding which is poleswitched by the method of amplitude phase shift keying. A drawback of the windings is that they have different energy indicators at different spin rates. In order to create rational diagrams with switching according to the number of poles, which is multiple of three, it is proposed to implement a polyphase MMF modulation of the three-phase winding. As a result of the study, there were procured the stator windings at 4 and 6 poles, which enabled to change the spin speed of the motor in the fan drives without breaking the drive power circuit by the scheme Δ / ΥΥ
